A package thief’s plan was foiled by a quick-thinking nanny, who ran out and tackled the crook in a bizarre encounter that was captured on home surveillance footage.

Sitter Kate Anderson was watching a 1-year-old at the Smith household in Everett, Wash., last Tuesday when she spotted a woman suddenly jump out of the front passenger seat of an SUV outside and snatched a large Amazon box – filled with presents for the baby — from the front door of the home.

“I saw her bending and picking it up, and they get a lot of packages. And I knew. I was like, ‘Oh my gosh – she’s taking that,’ so I just took off after her, to be honest,” Anderson told KIRO 7.

Surveillance footage posted on YouTube shows the thief, identified as 29-year-old Rhieanna Schindler, run away from the home with the package towards the waiting SUV, which had the passenger door open.

“Hey! What the f–k are you doing?” Anderson can be heard shouting.

As Schindler nears the car, she tosses the package inside and that’s when the car takes off, knocking Schindler off her feet.

“You f–king piece of sh-t. What are you trying to steal?” Anderson shouts as she nears the crook before tackling her.

The video shows Anderson continuing to hold on to Schindler and yelling for someone to call the police.

“Let go of me now! I didn’t do anything,” the package stealer claimed.

Anderson then fires back, “You know we got security cameras on this house,” as the mighty babysitter keeps a hold on her.

“Give up,” Anderson can be heard saying.

Minutes later, police arrested Schindler, who has more than 20 prior arrests on her record and had outstanding warrants for drug possession and theft, according to KIRO 7.

Anderson told the news outlet if she had to, she would thwart the thief again: “I didn’t ever feel like she was a threat to me. So I think I would’ve handled it the same way, yes, because it’s just not OK to go around doing that. It’s so not OK with me.”

The homeowner, Tanya Smith, told the network she was “very proud” of Anderson.

“She’s just like a straight baller, she’s amazing and doesn’t take any crap from anybody,” Smith said. “It’s pretty amazing what she did, I’m very proud of her, and I’m not surprised.”

The Snohomish County Sheriff’s office told KIRO 7 that it does not condone what Anderson did — but quipped that it’s hiring.
